Summary

The clinical difference (mean IOP, success rate, and complications) on using S2 and FP7 models of Ahmed Glaucoma Valve that had similar dimensions and different materials used for their construction in one year follow up was evaluated.

Conditions

  • Glaucoma, Open-Angle
  • Glaucoma Secondary
  • Glaucoma, Neovascular

Interventions

PROCEDURE

Ahmed Glaucoma Valve surgery

The surgical procedure was identical for both implant types and was performed as described previously.9,14 All surgical procedures were performed under local anesthesia except for children, general anesthesia was used. The valve plate was primed and placed in the superotemporal quadrant after making fornix-based conjunctival flap. The valve plate was secured to sclera with 10-0 nylon sutures 10 mm posterior to the limbus. Before implantation, applying sponges soaked with Mitomycin- c 0.3 cc for three minutes on bare sclera at this quadrant. The tube was placed in the anterior chamber through a 23-gauge needle tract at the limbus. The tube left patent and viscoelastic substance injected into anterior chamber. A donor scleral graft was secured with interrupted 10-0 nylon sutures over the exposed portion of the tube. Conjunctiva was sutured with 10-0 nylon sutures.
